Decompensated heart failure in a single center of a Latin American country: findings from the first 1595 cases in the ICARUS registry.

Abstract

Objective: Describe the methodological aspects, sociodemographic, and clinical characteristics of patients hospitalized with acute decompensated heart failure (ADHF) and their short-term outcomes.

Methods: Prospective cohort of patients with ADHF from the emergency service of the cardiovascular center. Descriptive statistics were used to synthesize sociodemographic characteristics, clinical characteristics during hospitalization, and outcomes.

Results: 1595 patients with ADHF. The median age was 68 years (Q1 = 58; Q3 = 76), and 69.28% were men. The median hospital stay was 6 days (Q1 = 4; Q3 = 11), with an cumulative incidence for re-hospitalization at 30 days of 8.70% (95% CI 7.18-10.40%), in-hospital mortality cumulative incidence of 4.33% (95% CI 3.38-5.44%), and a median change in the quality-of-life score Minnesota Living with Heart Failure at 30 days of -20 points (Q1 = -37; Q3 = -5). At discharge, all patients had a percentage > 70% of the use of quadruple neurohormonal blockade therapy.

Conclusion: Institutional aCute decompensAted HeaRt FailUre RegiStry (ICARUS) is one of the first studies in Latin America to demonstrate the importance of characterizing the population with ADHF and the adherence to heart failure guidelines may have influenced the favorable clinical outcomes.
